“We observed and treated a 42-year-old patient who complained a rapid onset of saddle hypoparesthesia and urine retention only a few hours after the spinal manipulation performed for L5-S1 herniated disc. The comparison of the two following MRIs performed before and after the manipulations seems to prove a close pathogenetic relationship.” Tamburrelli FC, Genitiempo M, Logroscino CA.
